Interesting... So the 30mm in AH's 109K-4 and the G-14 should be far superior to that in the Bf110G4 adn 190a8, then?
The K-4 and G-14 were much later in the war. Much better chance of them having the "latest and greatest" ammo, right?
I'm thinking it would be nice to know more about this, and perhaps have HTC change the modeling on the K-4 and G-14 30mm, to be the Ausf. C version

EDIT: Depending on dates, perhaps not the G-14, but the K-4, for sure!
